Application filed September 20, 1886. Serial No. 214,006.

To aZZ whom it may concern.-

Be it known that I, WALTER Soorr, of Plainfield, in the county of Unionand State of New Jersey, have invented an Improvement in RotaryPrinting-Machines, of which the following is a specification.

In printing newspapers it is often desirable to add a sheetorsupplement, and some weekly papers are larger than the daily paperspublished by the same parties.

The object ofthe present invention is to con nect two printing-presseswith sheet-delivery and folding devices in such a manner that thepresses can be run together when desired, and part of the paper will beprinted on one press and the remainder on the other press, and the twowill be brought together and laid in the proper positions for folding,and when desired the two presses can be run separately, thus allowingfor the two presses being used to the best advantage for the publisher,either by running them jointly or separately.

In the drawings, Figure l is a diagrammatic view longitudinally of thetwo presses. Fig. 2 is an end View illustrating the relative positionsof the presses, the rolls of paper and inking devices being removed.Fig. 3 indicates the different positions in which the sheets from thetwo presses can be brought together, and Fig. 4 represents thedirections in which the folding-blades can be made to act.

The upper press, A, and the lower press, B, are of ordinaryconstruction, except in the particulars hereinafter noted, and they areshown as duplicates one of the other, except that the upper press, A, isshown in Fig. 2 as nan rower than the lower press, B. They may,

however, be alike, or either one may be adapted to any desired kind ofbook, job, or newspaper Work, so long as the sizes and arrangements ofthe parts permit the two presses to be worked together, as hereindescribed.

The rolls of paper are shown at 1 1, the impression-cylinders at 2 2 forthe first impression, the fornreylinders at 3 3, the inking anddistributing rollers at 4 4, and at 5 5 are the conveying and secondimpression cylinders or drums. The second form-cylinders are shown at 66, and the inking devices for the same at 7 7.

The webs of paper are conveyed to the out (No model.)

present invention only relates to the means by which the sheets from thetwo presses are brought together and delivered to the folding device,which is shown at D, and may be of any desired character. I remark thatusually the press A will be upon a floor, 0, directly over the press B,for convenience in tending such press; but platforms may be used inplace of floors.

The two presses, when running together, are connected by the gear-wheels2O 21 22 23 with the driving-shaft 24, and the wheels 21 22 are movable,so that when the wheels 21 and are connected the presses will revolve atthe same speed, and when these are separated and the gears 23 and 22brought together the press A will rotate once for each two revolutionsof the press B.

The ranges of tapes orbelts pass over the pulleys 31 32 33 34, and therange of tapes or belts 35 pass around the pulleys 36 37 43,imposing-cylinder A, and pulleys 42, 40, 39, and 38, and the range oftapes or belts pass around the pulleys 46 47 48 49 41, imposing-cylinderB, and pulleys 40 and 39.

The parts are adjusted and fitted so that the sheet from B passes uponthe belts 45 between 49 and 51, along below the stationary guidebars 52and rollers 42, and belts 35 around second sheet can be laid on thefirst, and thenboth sheets can be passed ofi together, or else eachsheet can be passed ofi separately. In either instance the sheets passdown between tapes and 35, between the guide-bars 52 and the rollers 42,andalong between the belts 3'5 and45, around the pulleys 41,imposing-cyl-.

inder B, thence by the pulleys 40 over the parts are timed so as tobring the sheets from:

the two presses together, so that the sheets from A are laid upon thesheets from B.

dotted line 62 the position of the cutter 62, Fig. 1, is indicated. Thiscutter may be used to entirely separate the sheets longitudinally, ifdesired; or when this cutter is not used the first'fold of the sheetswill be on this central line, the second folds being in the lines of theblades 60 61.

Either press A or B can be used to print and deliver a four-paged paperwhen the press A is the same width as the press B. When the press A ishalf the width, the sheet delivered from the same will be two pages.When the forms on the press B are duplicated, then two four-paged paperscan be printed on B, and they are cut apart by the cutter 62.

The manner in which the papers from the two presses may be broughttogether is illustrated in Fig. 3. The six-paged paper is made by onenarrow sheet from A being imposed upon the widesheet from B, the partsbeing timed so that the-ends of the two sheets meet below the pulleys42. If an eight-page paper is to be printed, the two sheets from B maybe imposed one on the other as wrapped around the imposing-cylinder B,or one sheet may come from B and another from A if the two presses arethe samewidth. Where ten pages are to be printed,the press A is run athalf speed, and the sheet from A-meets the second sheetfrom B below thepulleys 42, and they are wrapped around B, upon the first sheet from B,which has before been wrapped around B, so that the sheet from A isbetween the two sheets from B, and then the sheets pass away togetherfrom B to the folding apparatus. Where twelve pages are to be printed,the presses are run at the same speed, and two sheets from A are wrappedaround A, and then pass together down between 30 and 35 and meet thesecond sheet from B below 42, and these are wrapped around B and uponthe first sheet from B, which has before been wrapped around B", so thatthe four sheets pass off together. Twelve pages may also be laidtogether in the same manner as ten pages, as before described, it thepress A is the same width as B, and sixteen pages can be laid togetherwith full-width presses by wrapping two sheets around A, so that theypass down and meet the sheets from B.. 1

It is to be understood that where'the press A is full width a half-widthweb can be used by arranging theforms in the middle parts of theform-cylinders in said press A.

The dotted lines in Fig. 1 indicate the gearwheels and trains of wheelsthat may conveniently be employed for connecting the respective parts,so that the motions may be positive and reliable. In cases where thepress Ais run at half the speed of the press B, by changing thegearing,as aforesaid,the gears that drive the belts 30 35 should bechanged so as to maintain the proper speed of these belts.

In instances where a narrow or single sheet 8o I and a double sheet havebeen folded together In Fig. 3 the line upon which the foldingblade actsis indicated at 60 61, and at the.

the narrow sheet has been made to lap past caught by such blade nearitsedge and carried to the folding-rollers. In this case the sheets do notproperly register. I avoid this difficulty by placing thesingle or halfsheet between the two whole or double sheets, as indicated in Fig. 3,for atenor twelve paged paper, or else the single or half sheet is nextto the rollers 66, as shown in Fig. 4, in order that under allcircumstances one edge of the single or half sheet may be in line withthe foldingblade 61, and a whole or double sheet may be next to theblade, so that in folding the paper the whole or double sheet carrieswith it the edge of the single or half sheet down into the bite of thefolding-rollers, and the operation is reliable and the registeraccurate.

By applying one or more paste-troughs and pasting-wheels in each press,as indicated at 68and 69, paste can be laid in lines on the edges orcenters of each sheet at the places where the folds are subsequentlymade, so that all the sheets can be pasted together. It is to beunderstood that these paste troughs and -wheels are of any ordinaryconstruction, and

that the paste-trough 68 will require to be lifted while the first sheetis passing under it, because the paste would be applied to that side ofthe sheet which forms the outside of the fold in the group of sheetsthat form what is usually known as a complete paper or signature. Thetapesare to be so disposed as not to come upon the paste-lines.

I do not limit myself to the particular devices shown, as any desiredcharacter of imposing-cylinders may be used, and transfercylinders andgrippers or rods are the wellknown equivalents of tapes, and may be madeuse of for performing the same duties. as some of the tapes.

In cases where two printing 'mechanisms have been used that print anddeliver sheets between converging tapes, such tapes bring the sheets toa common point of delivery, at which the sheets or set of sheets arelaid one upon another; but the sheet from one press cannot be laidbetween the two sheets from the other.

By the use of an imposingcylinder ('B or its equivalent) at or beyondthe junction of the paths over which the sheets are brought from the twopresses, the sheets can be laid upon paths for the sheets that-cometogether into each other in any desired order and one sheet from onepress laid between two sheets from the other press.

I claim as my invention-- 1. The combination, with two printingpressesand the belts or tapes forming two one path, of an imposing-cylinder, B,arranged to receive the sheets from that one path and impose the same inwhatever order they reach the cylinder from the respective presses, anda discharging mechanism to deliver the imposed sheets periodically,substantially as set forth.

2. The combination, with the two printingpresses, of the ranges 30, 35,and 45 of delivery-tapes and their respective rollers or pulleys,whereby one sheet of half width is laid upon and coincides with one halfof a second sheet of double width, rollers next to the single sheet, anda folding-blade acting upon the l middle of the wide sheet and on theline of one edge of the narrow sheet, to carry. both sheets through thefolding-rollers, substantially as set forth.

3. The combination, with two printingpresses for printing on two webs ofpaper, and cutters for separating the sheets, of changeable gearing toconnect such presses and regulate their relative speeds, tapes, pulleys,and cylinders for conveying the printed and cut sheets from the twopresses and bringing them together to form one paper or signature, andfolding mechanism for folding the sheets after being brought together,substantially as set forth.

Signed by me this 15th day of September, A. D. 1886.
